During use,the closable vent port provides air compensation when opened, andprovides a leak proof seal when closed. In embodiments featuring afiltered vent port, the air filter may or may not comprise a bacterialbarrier. By way of example, the filter may comprise a 0.2 micron filterfor air filtration providing significant bacterial protection.

In additional embodiments, the one-piece bottle includes a novel ventedcap that prevents bacteria from entering the bottle. The vented capallows the bottle to be filled with breast milk through the use of abreast pump that is attached to the cap in a leak proof manner. Thebottle may be connected—snapped or screwed on—to the breast pump andlater disconnected and recapped. Alternatively, the vented cap may bethreaded such that it may be loosened and removed from the bottle,thereby allowing a manual feed of either breast milk or other enteralfeeding solution, all without leakage. In manual feed embodiments, thecap may be tethered to the bottle such that it is not misplaced. Whenthe cap is removed, the breast milk or other enteral feeding solutionmay be poured directly into the bottle. Once capped, the bottle may bestored, frozen, and thawed with no exposure point until it is used forfeeding a baby. If no vent is provided, the cap may be cracked orloosened slightly in order to begin the flow of milk.
